I have free range birds and want to plant grass for them to forage on. Any suggestions as to what would be a good permanent grass to plant. I have planted annual and Abruzza Rye in the past, but the heat of Summer in Florida kills it. I need a good grass that will last year round. I have St Augustine in the yard, but that does not seem to interest them as much as the Rye. Thanks for any and all suggestions.I have a little Coastal Bermuda..too.
